WINDOW-PLATFORM AND Fl RE-ESCAPE.

SPECIFICATION forming part of Letters Patent No. 266,691, dated October31, 1882.

Application filed July 5, 1882. (No model.)

To all whom it may concern e it known that I, FRANK H. HniMsATH, ofChicago, inthe county of Cook and State of Illinois, have inventedcertain new and useful Improvements in Tindow-Platform and Fire- EscapeCombined; and I do hereby-declare that the following is a full, clear,and exact description thereof, reference being had to theaccompanyingdrawings, and to the letters of reference marked thereon,which forni a part ot' this specitication.

The object ot' my invention is to produce a scaiiold that can beattached to a window-sill', so as to form a platform exterior ofthewindow, that is provided with a railing, and is adapted for a person tostand upon while cleaning the windows, such scait'old at the saine timeto answer as a tire-escapei'orattaching a ropeladder. Therefore myinvention consists of the novel devices and combinations of deviceshereinafter described and specitically claimed.

In the accompanying drawings, Figure 1 represents a perspective view ot'the apparatus as used for a tireescape,and Figi) a similar View of theadjustable brace-foot.

Corresponding letters in the several tigures ofthe drawings designatelike parts.

A and A' are two frames, ol' triangular shape, that are bent each ot' abar ot'ilat iron, and of which a denotes the horizontal shank, b theperpendicular shank, ande the brace. The end ot' shank bis bent againtolap under shank a., and is connected therewith by rivets, while theinward end of such horizontal shank a is extended to reach over thewindow-sill, where each bar has adjustablyseeured byscrew-bolts aslotted L-plate, B, the pending shank ot' which is tapped for tighteningscrew C, that is to be turned against the window-frame for rig idlyattaching the scaffold. An angle-plate, d, is riveted against each shankb of frames A and A', under shank a., that will form a footsnpport uponthe outer edge ot' the windowsill. Against the lower end of bracecot'each frame A and A' is secured by screw-bolts a slotted angle'plate, D,which is to rest against the outer face ot' the building-wall, and isadjusted to sustain the bar a ot' the frames on a horizontal position.Upon the exterior end ot' each frame A and A' is secured a vertical bar,E, the lower end of which is bent rectangular and is riveted or boltedupon shank a ot' such frame. The upper end of each bar E has apunch-hole anda bracc-baigF,oi`round iron,that is tirst bent ushape, ispassed with its side shanks through the punch-holes of both bars E, soas to provide arigid connection between bars E. The two side shanks ot'bar F are curved downward, each to form a quarter-circle, and their endsare riveted to the top bars of trames A and A. rlhe upright bars E andthe brace-bar F will thus form a strong railing. Another lateral bar, G,is secured with its end under shanks a ot' frames A and A', thus rigidlyconnecting these frames, and this bar Cr is provided with two hooks, j',to which the rope ladder His or may be suspended.

A grate, l, is composed of two longitudinal bars, y, connected by aseries of lateral bars, h, that are riveted thereto, so as to form aplatform. The two barsg have each an eye to one end, by which they arepivoted upon a rod, t', that is secured between the extreme outward endsof frames A and A'. The most inward lateral bar, It', has holes di illedthrough its ends, through which the curved shanks of brace-bar F arepassed in a manner that such platt`orni,whi1e beingswungin eitherdirection, will follow the line of suoli curved braces, and will besteadied thereby. Such platt'orin l is turned down tlat upon frames Aand A' as long as the apparatus is to be used as a window-platform for aperson to stand upon, but will be turned upward to lean against thestandards E when the ladder H is to be attached and the apparatus is tobe used as a tire-escape, so as to provide sutticientrooin for a personto climb down upon the ladder.

The whole apparatus is to be made ot' steel or wrought-iron, so as tocombine the greatest strength with thc least weight, and thatit can behandled and attached easy by a single person.

The I -plate B, as well as the angle-plate D, being adjustable, thescaffold can be made to tit any building, and the whole device is veryconvenient for cleaning the windows, and is a safeguard for theinhabitants of the house in case ot' tire.

What I claim is- 1. A window-scaffold consisting of two tri angularframes, A and A', each composed of shanks a and b and brace c, andconnected by bars or rods G and t', and provided with ad- IOO e t266,69l

instable L-plates B, having fastening-screws (Land with adjustableangle-plates D, all substantially as and for the purpose set forth.

2. A Window-scaffold consisting of two triangular frames, A and A', eachcomposed ot' shanks a and b and brace c, and provided with adjustable Lplates B, havingfastening-screws (Land with adjustable angle-plates D,and being connected by bar G, having hooks f for suspending ladder H,the whole being constructed and arranged substantially in the manner setforth.

3. A window-platform consisting of two triangular frames, A and A', thatare provided with adjustable L-plates B, having fasteningscrews C, andwith adjustable angle-plates D, such frames being/connected by a rod,17, that forms the pivot fora platform, l,and by a bar, G, that hashooksf for suspending ladder H,

the Whole being arranged to operate substatitially in the manner and forthe purpose described and shown.

4. A Window-platform consisting of two triangular frames, A and A', thatare provided with adjustable L-plates B, having fasteningscrews G, withadjustable angle-plates D, and with standard-bars E and braces F, thatare connected by bar G, having hooks f, and by rod t', which forms thepivot forplattorm I, the whole being constructed and arrangedsubstantially as and for the purpose set forth.

In testimony that I claim the foregoing as my invention I aix mysignature in presence ot' two witnesses.
